Calculator is already exist but I developed it by adding new things for calculating (lenghts, areas...) just by me :) Pages: there is classic page uses for addition, subtraction... and others use for transformations!! How to Use Options: when you click on the bar, you will see every option with its number, type the item you want of those options in answer bar, for example: when you want the (km) option, write "1" #all #app #calculator #lenght #area #volume #time #tempurature #classic
